Reply to If you wrapped a human in a theoretical blanket that was able to insulate 100% of heat produced by the person, would that person’s body temperature eventually reach equilibrium, or would their metabolism cause them to keep getting hotter and hotter until they perish? by NonEuclideanGal
The reason people feel most comfortable around 25C (77F) is that this is roughly the equilibrium point, where the heat passively dissipated (no sweating, no wind blowing etc.) into the environment balances with the waste heat generated by the metabolism.

Free fall is equivalent to being in a region of space without gravity. Let's also assume a vacuum around it such that we can neglect external air pressure etc.
There is one force left, namely cohesion. It will attempt to minimize the droplet surface, morphing the it into a spherical shape. The pressure at the center is given by P= 4 gamma/R with R being the droplet radius. It is tiny for any sizeable droplet. It also gets smaller for larger droplets. until the droplet becomes massive enough to generate its own sizeable gravity.

Reply to Do males generally have a shorter life expectancy compared to females because of societal reasons or biological reasons? by Adiel482
Society mostly.
There is a series of 'cloister studies', i.e. following the life of nuns and monks. The interesting part here is that, not only do nuns and monks have a generally very healthy lifestyle (some labor, but not too hard, quality food, no dangerous activities etc.), but also males and females pretty much live the same life. The result is that monks have a significantly higher life expectancy than men in general, but it is still 1-2 years shorter than nuns.

Reply to comment by [deleted] in has the speed of light always been constant? by 2bornnot2b
This is a bunch of nonsense. You are conflating the speed of light with the speed of expansion (the Hubble 'constant').
